Solar panel installation factors

An accredited solar installer will make sure that solar panels are positioned on your roof for maximum efficiency, safety and correctly wired to the inverter.

Orientation and tilting

The basic condition of operating a solar equipment is to have the Sun shining on it.
It’s important to place the solar equipment so it gets most sun possible, during the full path of the sun. We recommend the angle of your absorber area to be close to 45 degrees. This will optimize the weaker ends of the season.
More information can be found in Solar Position menu.

Shading

PV panels should not be placed in shaded areas and should be kept free from dust and dirt. Shading from object such as trees, roof ventilators or antennas will have a large impact on the output of a panel, as it changes the flow of electricity through the panel.

Choosing a solar installer

A solar power system can be installed only by an accredited installer.

The accreditation scheme ensures that designers and installers of solar PV power systems:

An accredited designer or installer will provide you with a solar power system design and specification that includes consideration of your current electricity loads, the type of panels and inverter to be used and panel orientation.
